ALARM AND EMERGENCY suPP'L'Y FOR ANK DISPENSING nEvIoEs.

' Application filed rl'over'nber 10, 1927. SeriaINo. 232,454,"

The invention relates to dispensing devices for tanks and has particular reference toqthe fuel line of" automobiles and has for its object the provision of a receptacle through V which the? fuel passes from the fuel tank in'the automobile to reach the carburetor,

and providing an alarm that is operated by air passing through the fuel line after the fuel is exhausted to give notice to the operator of the vehicle that the supply of liquid in the tank is exhausted and at the same time provide him with emergency supply of fuel to enable him to reach a service station. j I

A further object of the invention is the provision of a partition in the receptacle arranged in the fuel line having an opening therein in which is arranged an audible i signal operated by air when the fuelin the storage tank is exhausted, the fuel serving to couplethe'signal while a supply of fuel 7 is passing through the receptacle; g

i The invention will be described in detail hereinafter-f and will be found illustrated in the accompanying drawings in which Figure 1 is a diagrammatic view ofa' fuel line for motor vehicles showingthereceptacle applied to the fuel line,

FigureQ is'a viewinsection on the plane indicated by the line 2-'2 ofFigure 1,

, Figure?) is a view in section on a plane indicated by the line 3-3 of Figure 1, and

Figure 4:, a view in section on aplane in- -'cated by the line ofFigure 2.

' In the drawings similar reference characters are used to designate corresponding parts throughout the several views.

In. Figure 1 is shown a conventional'fuel storagetank A and avacuum tank B and the alarm and emergency supply device des ignated gereally '0; Dis a pipe connecting the storage tank'A with thedevice C, and

- E is a pipe connecting the device O with the vacuum tank B. y

- As shown in the drawings the alarm and emergency supply device C is madeof two sections 1 and2 having their meeting edges 7 I Zflanged as shown at 3 and secured together therethrough by bolts or rivets suggested provided with apar'tition 5 having an open-V 'ing'Gtherein and? is a reed associated with l said. opening, said opening 6 and reed 7 i at 4, but it willgbe apparent that any other structure than that shown maybe used in place thereof. The part 1 of the tank C is a being so positionedinsthe partition 5 that when the liquid .fuel is regulated through the pipes. D and E and the device 0 the reed is submerged; withinthe liquid to prevent sounding," but when the liquid in the storage .tank, A-has been-exhausted and. air is pass ing through the pipes D and E tothe vacuum tank B, the reed will be agitated by the air passing through the partition above the q I 1 liquid in the tank to warn the operator of the vehicle that his supply of liquid fuel is exhausted. v o 7 To enable the operator to utilize the supply of liquidfuel that is in the device C, the pipe E is supplied with a valve 8 that is preferably arranged for convenient operation on the dash board of the'vehicleto close v the connection of the pipe E directly with the upper part of the device C5 so that the a liquid fuel may be drawn from the lower:

part of the receptacle by'means of-a. pipe-9,

thus providing an emergency supplyief liq-f uid fuel to enable the operator toproceedrto the next liquid fuel filling station to replenish hissupply of liquid fuel-inthestorage tank A. It will be understood that therecep-tacle C is to be arranged in any convenient position on the'automombileso that the valve 8 may be conveniently operated by the ratus.

It will also be understood that the appli f 'ance' may be used in connection with thedis-" f pensing pipes of tanks generally, especially where a pneumatic-system. is employed for discharging-the contents of the tank-and that the inventionis not'limitedyto its application in connection with the fuel line ofi m'otor vehicles hereinbefor-e specifically described. 1

What is claimed is 1.' An ala-rm'jfor ,tanki dispensing devices; comprising an emergency storage receptacle 1 adapted to be inserted in the dispensing line 7 intermediate of astorage tank, and a vacuum tank, a'partition 1n said receptacle extending a from the top thereof part way,to-its bottom,

the dispensingx line pipe connection being V arrangedon opposlte sides of saldpartitlon and an air operated signal arranged in said partition and operable only when Jth isfexhausted from the, storage tank.

2; An alarm for tank dispensingjdevices, comprising an emergencystoragereceptacle adaptedto be inserted in the dispensing line q'being arranged on opposite sides of said partition, the partition having an opening therein, anda reed arranged in said opening 7 ceptacle atfone side of the..-parti tion'= with a and operable only when the liquid is'exhau'sted from the storage. tank.-

V 3. An alarm for tank dispensing devices, comprising a receptacle, a partition arranged in said receptacle, a pipe connecting the restorage tank, another pipe at the other side Of the partitionconnecting the receptacle With a Vacuum tank to discharge liquid froinsaid receptacle, the partltlon aforesaid extending froinithe'topof the receptacle to-a P0111tbeloW- ,the connections of the pipes there ,With, a'valve in the last mentioned pipe, an

emergency discharge pipe connected with the last mentioned pipe and extending to the bottom of the'receptacle, and an ai'r'operated alarm in said partition.
